To all whom it may concern-.-

-Be it known that I, CORNELIUS J. \VILTSIE,

a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Adjustable Shade- Fixtures, of which the following is a full, clear, and exact specification.

The object of my in vention is to permit the carriers of adjustable shade-fixtures a limited lateral play without afiecting the relative position of the shade-roller hearings to said roller, so that the shade may always be paraliel to the window. This I accomplish by the means hereinafter fully described, and as particularly pointed out in the claims.

In the drawings, Figure l is a perspective view, on an enlarged scale, of the sliding carriers of an ad just-able window-shade, portions of the guide-rods upon which said carriers are mounted, and a shade-roller shown in dotted lines between them and having its central portion broken away. Fig. 2 is a horizontal section of the right-hand carrier, taken on the plane of the center of the bearing-block thereof. Fig. 3 is a similar view showing said bearing-block in a different relative position to said carrier. Fig. 4 is a side elevation of the left-hand carrier and a portion of the guide-rod upon which it is mounted. Fig. 5 is a horizontal transverse section of said lefthand bearing, taken on dotted line 5 5, Fig. 4, looking in the direction indicated by the arrows. Fig. 6 is a front elevation of an adj ustable shade-fixture embodying my invention, showing the portion of the brackets to" which the upper and lower ends of the guiderods are secured in section.

In the drawings, A represents the shaderoller, B and C the right and left adjustable sliding carriers having hearings in which the shade-roller is journaled, and D D represents the parallel vertical cylindrical guide-rods on which said carriers have sliding engagement. These guide-rods are placed one on each side of the window-frame and are preferably secured at the top and bottom, so as to have a limited lateral play, substantially as shown in the application for Letters Patent of the United States for curtain-fixtures filed by me August 12, l90l,-SerialNo.71,787,and asillustrated in Fig. 6 of the drawings.

, The carrier B is provided at each end with knuckles a and b, which engage the guiderods, and is provided with bearing-lugs c and b d, projecting therefrom near its upper and lower end in the same direction, in the alin ing bearing-apertures of which the pivotal studs eeof the hearing-block E arejournaled. The bearing-block E is preferably of such shape and dimensions that it can turn on the axis of its pivotal studs 6 e Without interfer ing with the frame of the carrier and is preferably supported by the carrier B in such manner as to be removable. I accomplish this removability by making the lower stud e shorter than the upper stud e and by mak-- ing the distance between the bearing-lugs of said'ca'rrier such that by raising the bearingblock sufficiently the lower pivotalstud can be lifted out of its bearings and the said' block tilted until it is in such position that when moved downward it will clear the lower bearing-lug and permit the withdrawal of its upper pivotal stud from its bearing. To do this, the pivotal studs must either be made tapering toward their extremities or their diameters must be less than that of the bearing-openings in which they are journaled. The carrieris raised or lowered on the guiderod D by means of a cord which is fastened in an openingfin a lateral offset 0 of the upper bearing-lug c, which is so constructed as not to interfere with the shade-roller during the operation of'rem'oving the bearinglolock thereof from said carrier. Bearingblock E is provided-with a transverse opening '11, the dimensions of which are rectangular, and it is adapted to receive the flattened end portion of the adjacent stationary springspindle r of the roller A, which latter may be thereof, and is provided with a tenon 2', pro- ICO jecting from the same edge at a point inediate said knuckles, which enters a longitudinal groove g of the guide-rod D, upon which said carrier slides. The body G of carrier C has a vertically-elongated bearing-opening k therein, the upper end of which is made of greater diameter. This construction of the bearing-opening is adopted so as to permit the enlarged head or extremity s of the revolving journal K of the contiguous end of the roller A to be inserted therethrough when the parts of the shade-adjuster are being assembled, so that when the journal is settled in the lower end of said bearing said head will prevent the accidental longitudinal withdrawal or dislodgment of the roller from the carrier. This carrier C is raised and lowered on the guide-rod D in the same manner as the carrier Bnamely, by a cord, the lower end of which is fastened in a suitable opening in a lug if, projecting from the upper knuckle of the carrier, as shown. Of course it will be understood that the vertical plane intersecting the centers of the bearings of the roller in both carriers B and G is the same distance from the axial center of their respective guide-rod, and it will also be apparent that regardless of the lateral play of the guide-rods or the rotative movement of the carriers the bearings of the shade roller (within reasonable limits, of course) will always he at right angles to the axial plane of the said shade-roller and said shade-roller will always be parallel to the plane of the window.

Another important feature of my invention .lS the ease with which the shade-roller can be inserted and removed from its bearings. In this respect my invention is unique, whether it is desired to remove one or both ends from its bearings.

What I claim as new is 1. In an adjustable curtain-fixtu re the combination with parallel guide-rods, carriers longitudinally adjustable on said rods, and a shade-roller the bearing of which in one of said carriers has a rotative movement the axis of which is parallel to the guide-rod.

2. In an adjustable curtain-fixture, the combination with the parallel guide-rods, longitudinally-adj ustable carriers one of which has a limited rotative movement about the axis of the guide-rod, and a shade-roller bearing carried thereby having an axis which is parallel to the guide-rod.

bination with parallel guide-rods, longitudinally-adjustable carriers one of which has a limited rotative movement about the axis of the guide-rod, and a shade-roller the bearing of which in said last-mentioned carrier has a rotative movement the axis of which is parallel to the guide-rod, and the journal in the other of said carriers is retained against accidental longitudinal displacement.

5. In an adjustable curtain-fixture the combination with parallel guide-rods, carriers longitudinally adjustable on said rods, a shade-roller,and a removable bearing-block in one of said carriers having a rotative movement the axis of which is parallel to the guide-rod.

6. In an adjustable curtain-fixture the combination with parallel guide-rods, carriers longitudinally adjustable 'on said rods, a shade-roller, and a bearing block in one of said carriers having pivotal studs journaled in said carrier whereby said bearing-block has a rotative movement the axis of which is parallel to the guide-rod.

7. In an adjustable curtain-fixt ure the combination with parallel guiderods, carriers longitudinally adjustableon said rods, one of which has bearing-lugs projecting therefrom and a removable bearing-block having pivotal studs projecting therefrom in vertical alinement and opposite each other the lower one of which is shorter than the upper, said bearingblock adapted to have a rotative movement the axis of which is parallel to the guide-rod.
